我有这个项目，它有后台函数和http函数。我还有用于单元测试的测试。CI/CD将使您在部署云功能时更加轻松

文件夹结构

|-- package.json
|-- cloudbuild.yaml
|-- functions
    |-- index.js
    |-- background
    |   |-- onCreate
    |       |-- index.js
            |-- create.js
    |
    |-- http
    |   |-- stripe
    |       |-- index.js
    |       |-- payment.js
    |-- utils
        |-- firebaseHelpers.js
    |-- test
        |-- ...
    |-- package.json

注意:utils/文件夹用于在函数之间共享代码

函数/ index.js

在这里，您可以导入所需的所有函数并声明它们。这里不需要逻辑。在我看来，这样更干净。

require('module-alias/register');
const functions = require('firebase-functions');

const onCreate = require('@background/onCreate');
const onDelete = require('@background/onDelete');
const onUpdate = require('@background/onUpdate');

const tours  = require('@http/tours');
const stripe = require('@http/stripe');

const docPath = 'tours/{tourId}';

module.exports.onCreate = functions.firestore.document(docPath).onCreate(onCreate);
module.exports.onDelete = functions.firestore.document(docPath).onDelete(onDelete);
module.exports.onUpdate = functions.firestore.document(docPath).onUpdate(onUpdate);

module.exports.tours  = functions.https.onRequest(tours);
module.exports.stripe = functions.https.onRequest(stripe);

CI / CD

每次将更改推送到回购时都进行持续集成和部署如何?你可以使用谷歌谷歌云构建。它是免费的，直到某个点:)检查这个链接。

。/ cloudbuild.yaml

steps:
  - name: "gcr.io/cloud-builders/npm"
    args: ["run", "install:functions"]
  - name: "gcr.io/cloud-builders/npm"
    args: ["test"]
  - name: "gcr.io/${PROJECT_ID}/firebase"
    args:
      [
        "deploy",
        "--only",
        "functions",
        "-P",
        "${PROJECT_ID}",
        "--token",
        "${_FIREBASE_TOKEN}"
      ]

substitutions:
    _FIREBASE_TOKEN: nothing

以上的答案为我指明了正确的方向，只是没有一个真正适合我。下面是一个工作原型，一个onCall, onRequest和数据库触发器的例子

foo.js - 随叫随到，随叫随到。

exports.handler = async function(data, context, admin) {
    // const database = admin.database();
    // const firestore = admin.firestore();
    //...
};

bar.js - onRequest

exports.handler = async function(req, res, admin) {
    // const database = admin.database();
    // const firestore = admin.firestore();
    //...
};

jar.js - trigger/document/onCreate .js

exports.handler = async function(snapshot, context, admin) {
    // const database = admin.database();
    // const firestore = admin.firestore();
    //...
};

index.js

//导入firebase管理SDK依赖项

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase); 

// import functions
const foo = require("./foo");
const bar = require("./bar");
const jar = require("./jar");

// onCall for foo.js
exports.foo = functions.https.onCall((data, context) => {
    return foo.handler(data, context, admin);
});

// onRequest for bar.js
exports.bar = functions.https.onRequest((req, res) => {
    return bar.handler(req, res, admin);
});

// document trigger for jar.js
exports.jar = functions.firestore
  .document("parentCollection/{parentCollectionId}")
  .onCreate((snapshot, context) => {
    return jar.handler(snapshot, context, admin);
});

注意:你也可以创建一个子文件夹来存放你的各个函数

在我努力实现@zaidfazil的解决方案时，我想出了以下方法(使用JavaScript，而不是TypeScript)。

multi.js

exports.onQuestionMultiCreate = functions.database
  .ref("/questions-multi/{questionId}")
  .onCreate(async (snapshot, context) => {
   ...
    }
  });

trueFalse.js

exports.onQuestionTrueFalseCreate = functions.database
  .ref("/questions-truefalse/{questionId}")
  .onCreate(async (snapshot, context) => {
   ...
    }
  });

index.js

const multi = require("./multi");
const trueFalse = require("./trueFalse");

module.exports = {
  ...multi,
  ...trueFalse

这种格式允许您的入口点查找其他函数文件，并自动导出每个文件中的每个函数。

主要入口脚本

找到functions文件夹中的所有.js文件，并导出从每个文件中导出的每个函数。

const fs = require('fs'); const path = require('path'); // Folder where all your individual Cloud Functions files are located. const FUNCTIONS_FOLDER = './scFunctions'; fs.readdirSync(path.resolve(__dirname, FUNCTIONS_FOLDER)).forEach(file => { // list files in the folder. if(file.endsWith('.js')) { const fileBaseName = file.slice(0, -3); // Remove the '.js' extension const thisFunction = require(`${FUNCTIONS_FOLDER}/${fileBaseName}`); for(var i in thisFunction) { exports[i] = thisFunction[i]; } } });

从一个文件导出多个函数

Const functions = require('firebase-functions'); Const query = functions.https。onRequest((req, res) => { Let query = req.query.q; res.send ({ “You searching For”:查询 })； })； const searchTest = functions.https。onRequest((req, res) => { res.send ({ "searchTest": "你好!" })； })； 模块。出口= { 查询 searchTest ｝

HTTP可访问端点有适当的命名

✔功能:查询:http://localhost:5001/PROJECT-NAME/us-central1/query function: helloWorlds: http://localhost:5001/PROJECT-NAME/us-central1/helloWorlds ✔功能:searchTest: http://localhost:5001/PROJECT-NAME/us-central1/searchTest

一个文件

如果你只有几个额外的文件(例如只有一个)，你可以使用:

Const your_functions = require('./path_to_your_functions'); For (var I in your_functions) { export [i] = your_functions[i]; ｝

更新:Typescript现在完全支持，所以不需要下面的恶作剧。只需使用firebase cli

以下是我个人是如何使用typescript的:

/functions
   |--src
      |--index.ts
      |--http-functions.ts
      |--main.js
      |--db.ts
   |--package.json
   |--tsconfig.json

在此之前，我先提出两点警告:

进口/出口的顺序在index.ts中很重要 db必须是一个单独的文件

第二点，我不知道为什么。其次，你应该完全尊重我的index, main和db的配置(至少要尝试一下)。

索引。Ts:与出口有关。我觉得让索引更干净。贸易部门负责出口。

// main must be before functions
export * from './main';
export * from "./http-functions";

主要。ts:处理初始化。

import { config } from 'firebase-functions';
import { initializeApp } from 'firebase-admin';

initializeApp(config().firebase);
export * from "firebase-functions";

db。Ts:只是重新导出数据库，所以它的名字比database()短。

import { database } from "firebase-admin";

export const db = database();

http-functions.ts

// db must be imported like this
import { db } from './db';
// you can now import everything from index. 
import { https } from './index';  
// or (both work)
// import { https } from 'firebase-functions';

export let newComment = https.onRequest(createComment);

export async function createComment(req: any, res: any){
    db.ref('comments').push(req.body.comment);
    res.send(req.body.comment);
}

@jasonsirota的回答很有帮助。但是查看更详细的代码可能会有用，特别是在HTTP触发函数的情况下。

使用与@jasonsirota回答中相同的结构，假设你希望在两个不同的文件中有两个单独的HTTP触发函数:

目录结构:

    /functions
       |--index.js
       |--foo.js
       |--bar.js
       |--package.json

index.js:

'use strict';
const fooFunction = require('./foo');
const barFunction = require('./bar');

// Note do below initialization tasks in index.js and
// NOT in child functions:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase); 
const database = admin.database();

// Pass database to child functions so they have access to it
exports.fooFunction = functions.https.onRequest((req, res) => {
    fooFunction.handler(req, res, database);
});
exports.barFunction = functions.https.onRequest((req, res) => {
    barFunction.handler(req, res, database);
});

foo.js:

 exports.handler = function(req, res, database) {
      // Use database to declare databaseRefs:
      usersRef = database.ref('users');
          ...
      res.send('foo ran successfully'); 
   }

bar.js:

exports.handler = function(req, res, database) {
  // Use database to declare databaseRefs:
  usersRef = database.ref('users');
      ...
  res.send('bar ran successfully'); 
}
